几种短效农药的残毒和防效试验

The Residues and Prevention and Control Test of Several Short-acting Pesticides

本文主要对溴虫腈、辛·溴、敌敌畏和辛硫磷等短效农药进行了防效和残毒试验。结果表明,溴虫腈对家蚕的残毒期最短,且溴虫腈和辛硫磷的混配组合在速效和持效以及残毒期等方面具有优势,表明溴虫腈在桑园中的应用前景良好。

This article mainly compared the residues and prevention and control test results of several short-acting pesti- cides as chlorfenapyr, octyl mercaptan, chlorfenapyr, dimethyl dichloroviny phosphate and octyl mercaptan. The results showed that the residues period of chlorfenapyr on silkworm was shortest, and the combination of chlorfenapyr and octyl mercaptan showed the better performance on quick acting, persistent effect and residues period. It was concluded that chlorfenapyr would have better prospects in mulberry fields management.
